A drill does its work at the most expensive moment in a part’s life. An aerospace or automotive component may carry hours of machining and weeks of lead time before a drill touches it. One failed tool can scrap all of it. Drill regrinding keeps that risk under control while carbide prices climb.

The Real Cost of a Dull Drill

With tungsten prices at record levels, the temptation is to push worn drills further and stretch the tooling budget. However, a dull drill wanders, work hardens the bore, and loads up until it breaks. The scrap cost of a nearly finished component dwarfs the price of the tool that ruined it. A controlled regrind program removes the gamble by returning sharp, verified tools to the floor on a schedule.

What Drill Regrinding Restores

Regrinding a drill is precision work concentrated at the point. GWS restores point geometry and concentricity, reestablishes the margins, and preserves the back taper the original design depends on. The reground tool cuts like the tool you first ordered. Our holemaking coverage includes high-performance drills, step drills, deep hole drills, reamers, and countersinks.

The more expensive the tool, the more regrinding saves. According to the Society of Manufacturing Engineers, sharpening and recoating a premium drill priced over $400 cost just $29. That is a saving of more than 90 percent.

Recoat Before You Recut

Holemaking concentrates heat and chip flow within the tool’s flutes, so the coating matters as much as the edge. GWS operates in-house PVD coating centers across our North American facilities. The same team applies the edge prep and coating your application requires, without a third-party queue. Established vendor relationships cover specialized treatments we do not run in-house.

Documented Quality for Critical Holes

Holemaking for aerospace and medical work demands paper as much as precision. GWS holds ISO 9001 certification, and independent third parties audit our quality controls. Every reground drill returns to the same documented standard as a new tool. We process, coat, and return most tools within two to three weeks, with a 72-hour option when production cannot wait. Custom inventory management programs keep large-volume users supplied without interruption.

Do not let a worn drill decide the fate of a finished part. Learn more about tool reconditioning at GWS, or contact us to build a regrind program around your holemaking tools. From Concept To Cut, GWS Delivers.
